Should You Take the ACT Science Section?

Marla Platt • May 28, 2026

ACT Science is now optional — but what does “optional” exactly mean?

Most students are surprised to learn that the ACT Science section is now optional. So should you take it or skip it ?


What the section actually tests

Despite the name, ACT Science isn’t about memorizing biology facts or chemistry equations. It tests data interpretation and scientific reasoning, so it is closer to reading comprehension than lab work. Students who handle graphs and experiments well often find the Science subsection more manageable than they expect.


Who requires it?

Very few schools require the ACT Science section. Only five colleges currently require it:


✓ Georgetown University

✓ Boston University

✓ Marquette University

✓ Pomona College

✓ East Carolina University


Carnegie Mellon, Duke, University of Michigan, and a few STEM-focused schools recommend it. Most schools (including Harvard, MIT, Stanford, and hundreds of others) treat it as truly optional. Penn State, Virginia Tech, Northeastern, and Wake Forest don’t consider it at all.


"Optional is not the same as irrelevant. Know the colleges on your school list before you decide."


Take it or skip it?

Take it if...

...Any school on your list requires or recommends it, you're applying to STEM programs, or you score well on practice sections.


Skip it if...

...Every school on your list marks it 'not considered' and your energy is better spent on the remaining core sections. Skip if practice tests suggest that you may not perform well on this section. When sending your ACT score to colleges, know that they will see your Science section if you sat for that portion of the test.


There is one more reason to take it even when optional: your college list may change. Having the Science score on file gives you some extra flexibility.
